when a vegetable gets put in salt water and collapses why does this happen
Answers
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.
How is gravitational lensing related to dark matter?
A.Dark matter emits lens-shaped rings of light.
B.The gravity of dark matter distorts light from distant sources.
C.The gravity of dark matter absorbs light from distant sources.
D.Dark matter uses gravitational lensing to create dark energy.
Answers
Answer: B) The gravity of dark matters distorts light from distant sources.
Explanation: In spite of the fact that stargazers can't see the dull matter, they can recognize its impact by seeing how the gravity of enormous world bunches, which contain dim matter, twists, and misshapes the light of more-far off systems situated behind the group. This marvel is called gravitational lensing.
The gravity of dark matter distorts light from distant sources.
What is gravitational lensing?Hubble's is perfectly adapted for examining the fascinating visual phenomena that gravity may produce when taken to its limit. The general theory of relativity developed by Albert Einstein describes how mass concentrations warp the universe around them.
When a massive mass of matter, such as a group of galaxies, produces a gravitational field that bends and magnifies light from distant galaxies that are in front of it but in the same line of sight, the result can be a gravitational lens.
Therefore, The gravity of dark matter distorts light from distant sources.

Answer:
Epidermis and Dermis
Explanation:
The two distinct layers of the integument consist of a layer of stratified squamous epithelium called the Epidermis and a deeper layer of areolar and dense irregular connective tissue called the Dermis.
The Epidermis is the outermost layer of the skin while the Dermis can be found under the epidermis and is also known as the thickest layer thereby providing strength to the skin
if an element has a half-life of 30 million years and there is 12.5% of it remaining in a rock, how old is that rock
Answers
Answer:
The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
After 3 million years you will have 12.5% of the original substance remaining.
And after 4 million years you will have 6.25% of the original substance remaining.

Answers
Answer:
The correct answer is edema.
Explanation:
When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.
However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.

Answers
Answer:
Early Eukaryotes were single-celled organisms that were present more than 1.6 to 2.1 billion years ago.
Explanation:
-Eukaryotes could be found in a variety of shapes and had a nucleus, a flexible membrane, and a cytoskeleton.
-Early eukaryotes used oxygen in metabolism.
Answer: Many traits found in eukaryotic cells today would have been found in early eukaryotic cells. First, early eukaryotic cells would have had membrane-bound organelles. Also, DNA probably contained introns since this is seen in many eukaryotic cells today. Chromosomes were probably linear in shape. Lastly, these cells would have had mitochondria and membrane-bound organelles. Since these are seen in all eukaryotic cells today, we can infer that they would have been around in early eukaryotes as well.

C.archaea,plantista,animalia
D. Life,animals,plants
Answers
Answer:
A. bacteria, archaea, and eukaryotic.
Explanation:
Bacteria, archaea, and eukaryotic are the three domains of life.
The three domains system was globally implied. The three domains were Archae, Bacteria and Eukarya. The correct answer is option A.
The three domains of Carl Woese's categorization system are archaea, bacteria, and eukaryotes. The six kingdoms are archaebacteria (ancient bacteria), eubacteria (actual bacteria), protozoa, fungi, plants, and animals.
This classification system divides life into several groups based on differences in the 16S ribosomal RNA (rRNA) structure, the lipid composition of the cell membrane, and antibiotic sensitivity. The main distinction from earlier classification schemes is the division of Kingdom Monera into Archaea and Bacteria.
Therefore, the names of three domains given by Carl Woese were Archae, Bacteria and Eukarya i.e. option A.

explain why a plant that does not get enough nitrate has weak growth
Answers
Answer:
Nitrate deficiency

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

Lysosome digest worn out cell and destroyed invading viruses and bacteria
Vacuole help to maintain water balance
Mitochondria is produced energy to cell in form of ATP
The graph below shows changes in the populations of two species that interact only with each other over a period of time.
Which statement best describes these two species?
Species A is a producer and species B is its consumer.
Species A is a host and species B is its parasite.
Species A is a predator and species B is its prey.
Species A is a scavenger and species B is its decomposer.
Answers
The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.
Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.
Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.
The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.
The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see
Species B thrive as the population of A remains lowFollowed by the steep decline of species B's population as more predators begin to appear. Once the population of species B reaches a critical point, species A will not have enough food supply to sustain its population, and both populations would decline.
This is exactly what the graph depicts, so option C is correct.
